Product Description

This product has the characteristics of low no-load loss, low no-load current, low noise, and significant power saving effect. It improves the voltage quality and the reliability of power supply. It is a green energy-saving device that is beneficial to the environment and is a new product that is popularized and used in urban and rural power grid technology transformation projects.
        The S13-M.RL and S11-M.RL series hermetically sealed three-phase three-phase wound core transformers produced by our company are different from the traditional planar laminated core transformers. The core is composed of three-phase column rails with three-dimensional triangular arrangement of single frame pieces. Each column is continuously rolled by a fine cold-rolled silicon copper thin strip, and the bandwidth is cut by a numerical control cutting machine in a straight line or a curve. The strip is wound on the core winding machine to form a nearly circular or folded arc frame piece Vacuum nitrogen filling annealing treatment to eliminate processing stress, character reorientation, improve magnetic permeability and improve electromagnetic performance; high and low voltage coils use special winding machine, directly wound on the iron core paper, the overall structure is solid and compact, the body is The upper and lower rails are insulated and laminated wood, and the screw rods are tightened around the coil to make it stable and reliable, and can withstand the impact of sudden short circuit.

Features

According to the current international GB / T6451-1999 "Technical Parameters and Requirements of Three-Phase Oil-Immersed Power Transformers" capacity 30-1600kVA, S13-M.RL series no-load loss decreases by 50% on average, and load loss decreases by 30% The M.RI series no-load loss decreased by an average of 30%, and the load loss decreased by an average of 25%.

Low no-load current

Due to the excellent material of the wound core and the characteristics of winding processing, the no-load current is significantly reduced. According to the current national standard GB / T6451-1999, S 13-M.RL series, the no-load current decreases by an average of 75%, S11-M.RL The series no-load current dropped by an average of 75%.

Low noise

According to JB / T10088-1999 noise standard, the noise of S13-M.RL and S11-M.RL series are reduced by about 7-9dB.

Strong short circuit resistance

The whole body of the transformer is in the shape of a triangular prism with pull bolts around and in the middle, which is integrated with the insulation of the upper and lower rails and laminated wooden blocks, which can effectively reduce the axial and radial mechanical stress during sudden short circuit.
